lmprovements` in Stills, of which the following is a specification.

M v invention relates to ati apparatus for distillation and its principal object is to provide a device wherebvthe process of distillation will be continuous, eitherfor wh e or partial distillation. I accomplish this by g means that are simple. and b v mechanical arrangements that are economical of construction and operation.

B v in v invention I use super-heated steam in pipes. or tubes. as a heating means. and by a mechanical means cause the material to he distilled to flow in a thin film down over the heated pipes. or tubes. The distillates so produced are carried to a condenser.A or to condensers if fractional distillation is desired. while the residauni ilows from the still through an outlet provided at or near the bottoni of the apparatus.

drawings. which illustrate an apparatus eonstrut-ted iii accordance with ni)v invention. and which form a part of this specification. In the drawings like numerals refer to like parts.

In the said drawings: Figure 1, is a side elevation with the casing b i'oken away showing the internal arrangement, Fig. '2, is an end elevation with the casing broken away showing the internal' arrangement, and Fig. 3, is a sectional detail view of a trough and partition.

I he numeral 1 i'epiesents a casing uttn end pieces 2 ot iron or any such suitable material; will M seen a portion of one of the ends 2 is hinged at 2* so that this part i ithin this casing 1 are may be moved. horizontal tubes. or pipes. 3 arranged one above the other and joined continuously to- .'ether :is shown by thereturn joints 4. The

. uppermost and the lowerinost of these pipes ointsasshown. and through the walls 5 of the heating chamber 6 and into said heating chamber, lwhere they are suitably connected with thelpipes which form the heating coil. Provision is made for admitting water into the pipes i of the heating coil as shown b v 'the pipes leading from the reservoir 9, and

in which and with suitable space apart are the valves 10 and 11, though any other well known and suitable device could be used. I have assumed that oil he used as a fuel for suppiying heat and in the drawings I have f means of supplyingr steam to the oil burner h'v the pipe 13 and the cock 1l. lthough it will be apparent that any other fuel adapted to any other well known furnace method could be used. suitable tlue/ 15 is provided leading from the combustion chantber. 13 is `an opening through which the. air for supporting combustion passes.

i 'ituin the casing l, and near its top. is a V-shaped Atrough ICL/with perforation.`- 1T l shown the ftt'el oil supply pipe 1'3 and a l l l along its bottoni, or the tingle of the said trough where its two sides meet. Leading into the trough 1G is the pipe 1S that is connected with the reservoir 19 provided to snppl)` the fluid to be distilled to the still. A suitable valve '21 is provided in this pipe 1S. i \Vitliin the casing 1 and at. or near, its hottoni is another trough QQ provided to receive Q3 that is provided with a suitable tra p il. At the uppei' part of the casing l is the otitlet pipe 25 provided to carry the distillatcs l to ain suitable condenser 2G.

For fractional distillate# I provide horifazontal partitions 'which art` adapted to be inserted in the c: sing l at suitable points as desired. One of these partitions QG I have shown in place in Fig. 1. and more in detail in Fig. 3. The partition 2li is provided with i a L l-shaped notch at QG' into which the bend i -t tits so as to permit the withdrawal of the partition. vIn detail the partition 2G has a 'i V-shapcd troughE 2.7 inserted at or near its 1 center willi pcrft'ipations 1T along the angle of the said trough where its two sides meet. These partitionsare designed to be inserted horizontally within the casing 1 between any series of the tnbe's 3 as may be desired with its trough part directly beneath the tube g above it. In the upper part ot' the chamber so formed within the casing 1 b'v the part outlet :29 for the distillatcs produced in that g chamber and leading to the condenser 31.

l For the purposes of illust rating the operaltion of in v invention. I will suppose that 'l petroleum is to be distilled, though it. will l be appartenu .tlliii'ti it can be adapted for use l in nio-st, if not all, processes where-distillal tion is carried jon.

K the residuuni and corr)v it to the outlet pipe y For a better tuioerstant'hng of my inven- -tioii reference is made to the accompanying 2 tition 26. as shown in Fig. 1, I provide an .a extend through the casing 1 at suitable the hydro-carbones of the. petroleum. The

Now oil is admitted from the resried to eonrlensers by outlets prov-ined from erroir 19 by ieansof the pipe 18. The oil each of the chambers made in the easing l will flow into the trough ltaml pass through by the insertion of the partitions.
